Our scheme is actually applicable to any type of quantum state - even DV based systems. Some DV systems, e.g. polarization,It is straightforward to alter polarization encoding into number-basis encoding or other forms of qubit encoding, e.g. [1]}. may need to be transformed first into the number basis.
In number-basis qubit-encoding, vacuum contributions enter directly, similar to what we have discussed earlier. In such schemes, the use of the TMSV entangled teleportation channel (a CV channel) can be utilized as the resource to teleport the DV qubit state [2]}, and so our proposed scheme operates directly. Our scheme also operates directly on more complex quantum states such as hybrid DV-CV entangled states - even on both components of such states [3]}. This flexibility of CV entanglement channels over DV entanglement channels is another advantage offered by our scheme.
